fully to comprehend the excellency of his divine genius, one must see
him, and hear him converse. His countenance speaks probity, and his
discourse discovers the deepest learning and the most sincere piety.
Think not that I only am his admirer; all learned and good men entertain
the same sentiments for him, particularly the King."

Casaubon writes to the President de Thou, April 20, 1613, to acquaint
him what pleasure he had received by seeing Grotius. "I must let you
know, says he, that I have seen here Hugo Grotius. He is a man of
admirable probity and learning[63]."

They had long conversations together on religion. Casaubon ardently
desired a reunion of the Protestants with the Roman Catholics[64]: and

imparted their thoughts to each other before the voyage to England: for
Casaubon congratulates him, January 8, 1612, on his desiring nothing but
peace and a coalition; and communicated Grotius' sentiments to King
James; who approved of them. This shews that Grotius thought it was
wrong to depart from the discipline and forms of the ancient church:
Casaubon was of the same mind; and his Letter to M. de Thou is a
demonstrative proof that these two excellent men did not differ in
matters of Religion. "I esteem him highly, says he[66], on account of
